Eucalyptus cinerea, also known as the silver dollar eucalyptus tree or argyle apple, bears pale, silver-blue leaves that fill the air with the scent of menthol. Silver dollar eucalyptus grows in U.S. Department of Agriculture hardiness zones 8 through 11, making it an ideal choice for ornamental landscaping in mild climates. Silver dollar eucalyptus typically propagates via seed, as growing from cuttings is often unreliable and difficult. Eucalyptus seeds germinate readily, and this fast-growing tree may reach 6 to 8 feet tall by the end of its first summer.

1

Fill the cells of a seed starter tray with a well-draining potting soil containing sand and perlite.

2

Sprinkle the eucalyptus seeds, and chaff if still attached, on the surface of the soil. Barely cover the seeds with sand. Press down on the seeds to tamp them into the soil.

3

Water the eucalpytus seeds from below by placing the tray in shallow water for about 20 minutes. Discard water remaining after that time.

4

Place the eucalyptus seeds in a warm, humid location. Ideal germination temperatures range between 68 and 72 degrees Fahrenheit. Humidity levels between 70 and 100 percent yield best germination results. Achieve these conditions with a humidifier or enclosed seed chamber if your area lacks these conditions. Germination takes about three months.

5

Put the seed starter tray in a cooler and sunnier spot once the eucalyptus seeds germinate. Temperatures between 55 and 60 degrees Fahrenheit for a few weeks result in thicker, stronger seedlings.

6

Plant seedlings in 1- to 2-gallon containers, containing potting soil with granular 5-10-10 fertilizer mixed in, when they reach 4 or 5 inches in height. Handle the seedlings by their leaves to avoid breaking the stem.
